To determine whether the square root of 9 is a rational number, we need to understand what a rational number is. A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
In this case, the square root of 9 is √9. When you calculate √9, you get 3, which is an integer. Since 3 can also be expressed as the fraction 3/1, where the numerator and denominator are both integers, we can conclude that the square root of 9 is indeed a rational number.
To solve this, you can use a calculator to find the square root of 9, or you can remember that the square root of a number is a value that, when multiplied by itself, equals the original number. In this case, √9 can be calculated by finding a number that, when multiplied by itself, equals 9.
